2.54.6.Nullable Types Assignment

using System;



class MainClass

{

   static void Main()

   {

      int? nullableInteger1, nullableInteger2, nullableInteger3;



      nullableInteger1 = 28;

      nullableInteger2 = nullableInteger1;

      nullableInteger3 = null;



      Console.WriteLine("nullableInteger1: {0}, nullableInteger2: {1}", nullableInteger1, nullableInteger2);

      Console.WriteLine("nullableInteger3 {0} null", nullableInteger3 == null ? "is" : "is not");

   }

}

nullableInteger1: 28, nullableInteger2: 28
nullableInteger3 is null
